What this word exactly mean mountain-springs?
Springs are small streams of water flowing naturally from the earth. So mountain springs are the same thing, just in the mountains.
Reply:It refers to the small body of water that usually gushes from rock crevices or mountain sources.
Reply:In the case of the thermal springs in the Rockies, their formation tends to be quite consistent. As rain falls on the surrounding peaks, it percolated into the rather porous sedimentary rocks. As it descends through the rock, it picks up a variety of materials, everything from radium to sulphur. Also, as it moves further beneath the surface, it heats up from the primal heat of the Earth. Eventually, it encounters a large thrust fault, or crack. As water descends behind it, it forces the now heated water to ascend along the fault-line to surface as a hot or warm spring.
